1,1-dimethylethyl [3-({[4-(chloromethyl)phenyl]carbonyl}amino)biphenyl-4-yl]carbamate (20 g, 45.8 mmol), potassium phthalimide (9.33 g, 50.4 mmol) and potassium iodide (1.52 g, 9.15 mmol) were stirred in DMF (81 mL) at 50° C. overnight. Room temperature was attained, H2O was added and the products extracted into EtOAc (×2). The combined organic extracts were washed with brine, dried over MgSO4 and concentrated in vacuo. The residue was triturated in MeOH to give 1,1-dimethylethyl {3-[({4-[(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)methyl]phenyl}carbonyl)amino]biphenyl-4-yl}carbamate as a pale yellow solid.
